(H&E,× 40)(B) The tumour cells were round or polygonal with abundant eosinophilic cytoplasm, hyperchromatic nuclei and prominent nucleoli; and numerous mitoses can easily be found(H&E, × 200). (C-F) In accordance with the frozen section of ovary tumour (C, H&E, × 200; D, H&E, × 400), these images consist of multilocular cysts and necrosis (E, H&E, × 100) and atypical cells (F, H&E, × 400). G-I CSCC in bilateral fallopian mucosa and the right fimbrial end (H&E, × 40). J-K CSCC lived on the endometrium surface diffusely.(H&E,× 40)
